   Hi, @caishunfeng @DarkAssassinator 
   BTW, i think current table structure of `t_ds_environment` is not elegant, 
as far as I know, environment just configure some environment variables which 
may be used in tasks. Why not record a variable in one row, rather use `config` 
field? Only query this table once during task execution, so query performance 
is not a big deal.
   
   Also, i have an environment-related question, in 
https://github.com/apache/dolphinscheduler/issues/12713#issuecomment-1317967932,
 wish you could give some suggestions!
